Hidden City Adventures provide an option of three treasure hunts taking you around different parts of London, guided by clues sent to your mobile phone. The one we chose to do was Moriarty's Game, a Sherlock Holmes type mystery that led us around Fitzrovia and Mayfair.
The walks are set in the real world and do involve you interacting with various people along the way -such as going up to a barista in a certain coffee shop and telling them that the white knight sent you (not an actual clue, by the way!). It will involve real detective work and the clues are quite challenging, but this all adds to the sense of achievement when you actually figure them out. You should think of the experience as a day out, rather than a brisk walk, because although we covered a distance of 3km, it took us around three hours with breaks for drinks or snacks as we sat and worked on the various clues.
The games have been set up with great care by people who are interested in London because they bring you through surprising areas and spaces that you would not otherwise see. I have lived in London almost my entire life and there were some places that I didn't realise existed right in the heart of town. I would say, that it is a social activity - best undertaken with at least two or possibly a small group - as working out the fiendish clues together can be a fun, bonding experience. Also, you should be aware that you will need to add the cost of stopping for coffee or drinks, two or three times during the walk, to your budget for the day.
Having said that, this is a great day out for the over 55's because it involves a small amount of exercise, that you can take at your own pace. It has great puzzles that will stimulate your brain. It is a good social activity, that involves interacting with both unknown people and members of your group, you get a nice sense of achievement when you complete it, and most of all it is fantastic fun!
